Seabed Morphology and Geomorphology of Beagle Marine Park

2021 data from the Beagle Marine Park in south-eastern Australia provides geospatial seabed morphology and geomorphology information. The dataset was created by the Australian Ocean Data Network and collaborators using a two-part classification system applied to bathymetry digital elevation models. It includes features mapped at broad (30 m) and fine (1 m) horizontal resolutions.

Use Cases

• Classify seabed Morphology Feature types like topographic highs and lows using geometric attributes derived from bathymetry DEMs.
• Interpret seabed geomorphology by integrating backscatter intensity, seabed imagery, and sediment samples with morphology classifications.
• Analyze seabed feature distribution at multiple resolutions, comparing broad-scale (30 m) layers with fine-scale (1 m) DEM-derived layers.

Strengths

• Applies a nationally consistent two-part seabed geomorphology classification system.
• Includes multi-resolution mapping with data derived from 30 m and 1 m horizontal resolution DEMs.
• Supplemented by additional datasets like backscatter intensity and seabed sediment samples.

Limitations

• Specific row count, column count, and total spatial extent are unknown.
• Geographic coverage is limited to the Beagle Marine Park in south-eastern Australia.
• Data currency is unclear beyond the 2021 survey report informing the features.
